Liquid Blend shall be completely blended at terminal under supervision of authorized Quality Control personnel. No additives, modifiers, or extra ingredients are to be introduced into the MATREX Liquid Blend at any time after shipment from terminal. A copy of the bill of lading and material certification shall accompany every shipment. MATREX Liquid Blend shall be shipped in insulated tankers to maintain oil temperature during transportation.
PLANT MIX The cold mix shall consist of aggregates meeting material section A) Aggregate and the bituminous MATREX Liquid Blend meeting material section B) Bituminous material as indicated in the proposed job mix formula. Bituminous material shall be accepted at the supplier’s source and at the plant site on the basis of a supplier material certification. The preferred mixing ratio shall be 5.5% MATREX Liquid Blend or 110 lbs. per finished ton (2000 lbs.) of mixed material. Continued onsite testing will determine exact final mixing ratio, which will be identified in the final job mix formula. All
aggregate percentages are based on the total weight of the
aggregate. The job mix formula information shall provide:
PLANT PREPARATION AND OPERATION The mixture is to be produced through a conventional hot asphalt plant or approved modified pugmill under the direct supervision of a qualified quality control representative. The bituminous MATREX Liquid Blend shall not be heated above 140° C (300° F). The final mixture must be tested in accordance with Matrex Company’s Quality Control requirements.
STOCKPILE INSPECTION Prior to production the stockpile site is to be inspected for any contaminants such as dirt, sand or debris that may affect the quality of the MATREX Performance Cold Patch. The stockpile area should be a hard surface, preferably paved with concrete or a bituminous surface.
SPECIFICATION SAMPLING A quart sample of the MATREX Liquid Blend will be retained at the asphalt depot prior to shipping. On delivery of the tank truck, an authorized representative of the Matrex Company will take an additional quart sample. This sample will be returned to the laboratory for testing to ensure no contamination has occurred in transit.
MATREX QUALITY CONTROL On each load an authorized representative of the Matrex Company will prepare a quality control report. All phases of production of the plant operation and the material testing on each 150 ton of production will be prepared and entered accordingly in each category. The following site tests will be completed including Spot Test, Strip Resistance, Coating, Observation, and Roll Test. Typical one-quart sample will be forwarded to the Matrex Company for laboratory testing and review.
TRAINING OF INSTALLATION CREWS The successful bidder must make available a complete training program for all road crews to insure correct patching methods along with updates on the subject. In addition, the supplier must provide an installation chart to the volume of material required to repair utility cuts and other excavated areas for references by installers.
QUARTERLY FIELD INSPECTIONS MATREX stockpiles will be inspected every three-months by an authorized representative of the Matrex Company, who will perform ASTM D-1664 coating and stripping tests on the MATREX Permanent Cold Patch. Any unsuccessful tests will resolve in re-examination by the technical section to examine the material. Any failed product will not be shipped until the Technical section has completed written authorization. The Matrex Company for future reference will maintain records. A representative of the company must approve the final mixture.
STOCKPILING MATREX may be stockpiled for up to 2 years in an uncovered outdoor stockpile.
TESTING After the cold mix is manufactured through the approved plant, three further tests are conducted to meet specifications: ASTM D-2172 Extraction of asphalt 4.5 — 7% Maximum ASTM D-1664 Coating and stripping tests for both wet and dry aggregates The cold mix, 50 grams is put into 400 ml. of distilled water in a beaker and boiled for 3 minutes and stirred at 1 revolution per second. Retained coating must be in excess of 95% for passing. Each bidder must supply certified independent laboratory testing that the Permanent Cold Patch has passed the OPSS1153 stripping test 1153.08.01.01 testing. LIFETIME PERFORMANCE GUARANTEE
MATREX Permanent Cold Patch when applied according to our directions to deteriorated concrete or bituminous pavement surfaces is guaranteed to adhere permanently to the repair area for the life of the repair or until the surrounding pavement area failed. The Matrex Company will replace actual tonnage of MATREX at no charge for any MATREX Permanent Cold Patch that should ever ravel or release from the area. MATREX
