638-2.06 Tack Coat. The tack coat shall be supplied by a manufacturer appearing on the Department's
Approved List of Synthetic Resins. The tack coat shall conform to the requirements of §702-71. The tack coat material shall be available 10 days prior to production of the mix so representative samples of the tack coat can be obtained by the Engineer and tested by the Materials Bureau for conformance of §702-71.
638-3 CONSTRUCTION DETAILS. Except as provided in this specification, the construction
requirements shall meet those of §404-3, Asphalt Pavements - Construction Details.
638-3.01 Weather Limitations. The requirements for top course mixes in §404-3.01, Weather and
Seasonal Limitations, shall apply.
638-3.02 Preparation of Mixture. The mixing plant shall meet the requirements of §401-3.08 unless
otherwise approved by the Director, Materials Bureau. Before the pugmill is allowed to produce white synthetic resin binder concrete, it shall be thoroughly cleaned by charging a minimum of two (2) successive batches of hot dry aggregate into the pugmill and mixing each batch for a minimum of four (4) minutes. In addition, the first batch of white synthetic resin binder concrete produced, after a change from normal asphalt concrete production, shall not be incorporated into the work. Such batches shall be at least fifty (50) percent of the rated pugmill capacity. This batch may also be used for the first material passed through the paver as described in §638-3.04, Paving. The white aggregate shall be introduced into the pugmill, between the limits of 250°F to 350°F and the temperature of the synthetic resin binder (one component) shall be maintained between the limits of 260°F and 300°F. When the binder is added directly into the pugmill in cold, prepackaged units (two components), the temperature of the aggregate may be increased accordingly to meet the specified mix temperature, but shall not exceed 425°F. For either method of binder addition, the resulting mix temperature shall be in the range of 250°F to 325°F. The pigment, resin chips, plasticizing oil and hydrated lime shall be added to the pugmill in whole bag units. If the pigment and/or hydrated lime is not delivered from the manufacturers as whole units, the Contractor may weigh and repackage in a manner approved by the Engineer so that the pigment and/or hydrated lime may be added as whole units. The hydrated lime may be added in a manner approved by
638-3.03 Preparation of Surface.
NEW YORK STATE DEPARTMENT OF TRANSPORTATION Section 600 STANDARD SPECIFICATIONS (USC) January 1, 2026 VOLUME 3 the Engineer, if difficulties are encountered in maintaining the specified mix temperature when adding the hydrated lime directly to the pugmill. Batching and mixing requirements for the White Synthetic Resin Binder Concrete are as follows:
A.One Component Binder. After the hot aggregate is discharged into the pugmill, add the pigment and hydrated lime in whole bag units as required and dry mix for a minimum of 15 seconds. After the dry mix the synthetic resin binder should be added and wet mixed for a minimum of 45 seconds.
B.Two Component Binder. After the hot aggregate is discharged into the pugmill add resin chips in whole bag units as required. This should be immediately followed by the addition of the hydrated lime in whole bag units and dry mixed for 30 seconds. Following the dry mix add the plasticizing oil and pigment in whole bag units in that order and wet mix for 30 seconds after all components are in the pugmill. Any increase in pigment content above that specified on the job mix formula for the convenience of mixing shall be made at no additional cost to the Department. The pigment content may be increased within the general limits, as directed by the Engineer, to obtain a satisfactory color during production.
638-3.03 Preparation of Surface. All surfaces to be paved shall be thoroughly cleaned of all foreign
material, including membrane curing compound of Portland Cement concrete pavement, prior to the placing of the pavement. A tack coat, consisting of a uniform application of rapid curing synthetic resin liquid, §702-71, shall be applied at a uniform rate between 0.03 to 0.05 gallons per square yard over the areas to be paved. The tack coat shall be applied with either a paint roller or spray unit to assure uniform application. The tack coat shall not be poured onto the pavement surface for application. After the tack coat application, curing time shall be sufficient to permit the coating to become tacky before paving. No traffic shall be permitted on the tack coated surface.
638-3.04 Paving. The mix shall be laid between the temperatures of 250°F to 325°F as specified by the
Engineer. All areas of uniform width of 4 feet or more shall be paved with an approved paving machine. Areas of narrow or variable width may be placed without a paver but in a manner approved by the Engineer. All paving edges shall be formed in a manner approved by the Engineer to obtain a true edge. The equipment including trucks, paving machine rollers and tools which come in contact with the white synthetic resin binder concrete shall be thoroughly cleaned before use. In addition, the paving machine shall be cleaned of excess asphalt by spraying with solvent. This shall be directly followed by the passage and subsequent wastage of at least one (1) ton of the white material. The material may be from the same batch used to clean the pugmill.
638-3.05 Compaction. Provisions of §404-3.07 Compaction shall apply except that a minimum of two
passes of a nominal 10 ton steel wheel tandem roller shall be used for compaction. The edge forms shall be removed prior to applying the second roller pass. This shall be done as expeditiously as possible so that the second roller pass is completed while the mat is still hot. Forms used for the formation of transverse drainage troughs shall be kept in place until the completion of all rolling operations. Narrow areas which are subject to overstressing with a 10 ton roller may be rolled with a small roller as approved by the Engineer. The paving edge forms shall be removed prior to applying the final roller pass with the small roller as previously described for the 10 ton rollers. The use of a pneumatic tire roller will not be required for this item.
638-4 METHOD OF MEASUREMENT. The quantity of white synthetic resin binder concrete shall be
measured by the number of tons of compacted material in place.
