Bituminous Pavement Sample Clauses
Bituminous Pavement. All main roads in plant area subjected to truck traffic shall be designed for a minimum of two passes of an AASHTO HS-20 loading per day. Automobile parking area shall be 2" of bituminous concrete over 8" thickness of base course material. Base course material shall conform to State of Texas and county requirements for Highway and Street Construction.
Bituminous Pavement. Materials testing and inspection for bituminous pavement, (including Asphaltic Concrete Drainage Course), is the responsibility of the Contractor. The Contractor shall perform all materials testing at the prescribed frequency to determine compliance with design parameters for gradation, percent crushed aggregate, moisture, density, and asphalt density. The Contractor shall be responsible to make density determinations of the compacted pavement. One test shall be made on each lift of base and surface course for each 500 feet of lane placed. The location of tests shall be as directed by the Engineer. Tests shall be made using a nuclear device in accordance with ASTM D 2950. Test data shall be recorded and a copy furnished to the Engineer on a daily basis whenever pavement is placed. Readings shall be made in the presence of the Engineers inspector when required by the Engineer. In the event readings show insufficient density of in-place pavement, the Contractor shall make additional readings as directed by the Engineer, at no added cost. Pavement materials and/or methods of mixing or placing shall be revised if determined by the Engineer to be necessary based on readings or trends in readings. The Authority reserves the right to require removing and replacing areas of pavement where the average of in-place density tests is less than approved laboratory density. Density testing shall be considered subsidiary to bituminous paving. For verification of weights and measures, character of materials, and determination of temperatures used in the preparation of the paving mixes; the Authority or its authorized representatives shall at all times have access to all portions of the paving plant, aggregate plant, storage yards, and other facilities for producing and processing the materials of construction. All sampling and testing of processed and unprocessed materials shall be under the control and direction of the Authority at all times. Arrangements shall be provided for securing representative aggregate samples from each of the hot bins by installing convenient doors in the plant housing, and making any other necessary provisions. If these arrangements are unsatisfactory to the Engineer, the Contractor shall, under the direction of the plant inspector, pull dry samples from the bins through the mixer into a clean truck, and quarter and re-quarter as frequently as required.
