1055.2 Procedure

1055.2.1 Clear or Transparent Liquid and White Pigmented Curing Compounds

1055.2.1.1 Pre-Acceptance Lists

Manufacturers and Brand Names of white pigmented liquid membrane curing compounds and clear or transparent liquid membrane curing compounds will be placed on the Pre-Acceptance List maintained by the State Construction and Materials Engineer in accordance with EPG 1055.2.1.2 Manufacturer and Brand Name Approval, below, and the applicable specification. These lists are found in the Pre-Acceptance Lists & PAL Forms and on MoDOT’s web site.

1055.2.1.2 Manufacturer and Brand Name Approval

If a manufacturer desires to have material added to the Pre-Acceptance List of qualified curing compounds, a certification and guarantee must be submitted to the State Construction and Materials Engineer in accordance with the requirements of Sec 1055. The certification and guarantee shall be accompanied by a one-quart (1 liter) sample of curing compound. Upon approval of the curing compound, it will be placed on the applicable list. Further certification is not required.

1055.2.1.3 Basis of Acceptance

Material is accepted by the PAL criteria as indicated in EPG 106.12 Pre-Acceptance Lists (PAL). The State Construction and Materials Engineer will retain the original certification and guarantee. Additional certification is not necessary if the manufacturer and brand of material is clearly identified on the container or the documentation included with bulk shipments.

All storage tanks shall provide a means for sampling and for mechanical mixing to prevent settling of material. In addition, a project storage tank shall provide a metering device so that all material for the project may be metered into the spray apparatus to determine coverage rates. Material stored for the project shall be mixed thoroughly by the means designated by the manufacturer, prior to unloading for use at the paving site. Only approved material of the same brand and manufacturer may be mixed in any transport or storage.

1055.2.1.4 Sampling

Samples may be taken at the manufacturing plant, warehouse or, if necessary, at the point of delivery. The sample should be taken from a single container (or from the flow line while filling a single container) representing a specific container for each lot, batch or other unit of production in a shipment.

1055.2.1.5 Manufacturing Facility

Each curing compound manufacturer will be assigned to a district office for Facility Review, Sampling and Testing in accordance with EPG 106.12 Pre-Acceptance Lists (PAL). During the visit, samples of material available at the facility shall be obtained. Material originating too far from the assigned district’s office is subject to sampling at an intermediate location or at the job site. It is the assigned district’s responsibility to verify with the supplier that the location selected for sampling is acceptable to the supplier as a location from which a valid PAL source sample may be obtained.

1055.2.1.6 Sample

A sample of curing compound shall consist of one quart (1 liter) of material in a screw top can. All samples shall be obtained by the manufacturer or contractor’s agent in accordance with the manufacturer’s sampling instructions. The inspector will observe the sampling process. The sample shall be recorded through AASHTOWARE Project (AWP) showing the manufacturer's name, the brand name and designation of the material, lot number, net quantity represented, and the location where the sample was obtained using the Sampled From and Sample Origin fields of AWP. The Other tab is also used for a Mixing Facility. The PAL ID number obtained by the supplier in accordance with EPG 1055.3.1 Clear or Transparent Liquid and White Pigmented Curing Compounds should be recorded in Site Manager in the “Link To” field.

1055.2.2 Dissipating Curing Compound

1055.2.2.1 Manufacturer and Brand Name Approval

The list of qualified dissipating curing compounds is found in the Job Special Provision (formerly Bridge Special Provision) in the contract.

1055.2.2.2 Basis of Acceptance

Material is accepted based upon inclusion on the qualified list. Certification is not necessary if the manufacturer and brand of material is clearly identified on the container or the documentation included with the bulk shipments.

All storage tanks shall provide a means for sampling and for mechanical mixing to prevent settling of material. In addition, a project storage tank shall provide a metering device so that all material for the project may be metered into the spray apparatus to determine coverage rates. Material stored for the project shall be mixed thoroughly by the means designated by the manufacturer, prior to unloading for use at the job site. Only approved material of the same brand and manufacturer may be mixed in any transport or storage.

If the shipper requests, the material will be assigned a PAL ID per EPG 1055.3.1 Clear or Transparent Liquid and White Pigmented Curing Compounds.

1055.2.3 Waterproof Paper, White Polyethylene-Burlap Sheeting, and Burlap and Mats

1055.2.3.1 Basis of Acceptance

The Supplier shall provide evidence that the Material conforms to the specifications as defined in Sec 1055.

1055.2.3.2 Sampling

Sampling will be designated by the State Construction and Materials Engineer or when specification compliance is suspect. When a shipment is sampled, the number of rolls to be sampled is one-half the square root of the number of rolls, rounded to the nearest whole number, in the shipment. A sample is to consist of a strip 18 in. (450 mm) long by the width of the roll and is to be cut at least 5 ft. (1500 mm) from the end of the roll. The samples are to be submitted to the Laboratory for testing and identified through AWP.

1055.3 Sample Record

1055.3.1 Clear or Transparent Liquid and White Pigmented Curing Compounds

Test results shall be reported by the Laboratory in accordance with EPG 1055.4 Laboratory Testing Guidelines for Sec 1055 and EPG 106.12 Pre-Acceptance Lists (PAL).

For material shipped directly to a job site by a supplier, the supplier shall notify the State Construction and Materials Engineer prior to shipment using GS-13 Form 3. When complete and correct information on the shipment is provided to the State Construction and Materials Engineer, a PAL ID number will be assigned to the material. That number shall be attached to the material or container and stay with the material until it is consumed.

Material purchased for maintenance work may be accepted solely on the basis of the PAL supplier, or manufacturer and brand being on the Pre-Acceptance List. District materials will report the receipt and acceptance of the material in AWP and will mark the material or containers with the sample ID number they assign.

1055.3.2 Dissipating Curing Compound

A sample record as described in AWP MA Sample Record, General and including the Free Form Test will be created for any material accepted on the job on the basis of certifications, label, or invoice.

If the shipper requests, the material will be assigned a PAL ID per EPG 1055.3.1 Clear or Transparent Liquid and White Pigmented Curing Compounds.

1055.3.3 Waterproof Paper, White Polyethylene-Burlap Sheeting, and Burlap and Mats

Test results shall be reported by the Laboratory in accordance with EPG 1055.4 Laboratory Testing Guidelines for Sec 1055 and EPG 106.12 Pre-Acceptance Lists (PAL).
