Evaluation of bituminous mixes in pavement structures interim report IV - Development of surface deformations at statehighway 51 pavement test sites
(Jul-76)The development of rutting and other deformations in the pavement surface of two sites on a new section of State Highway 51 was monitored for a two year period. Transverse profile tracings, core samples, surface nuclear ... -
DEVELOPMENT OF AGGREGATE CHARACTERISTICS-BASED PREVENTIVE MAINTENANCE TREATMENTS USING 3D LASER IMAGING AND AGGREGATE IMAGING TECHNOLOGY FOR OPTIMIZED SKID RESISTANCE OF PAVEMENTS (FHWA-18-05)
(Jun-19)The objective of this study was to assess the skid resistance performance of pavements in Oklahoma following preventive maintenance treatments. The assessment method employed herein was based on physical aggregate properties ... -
Evaluation of bituminous mixes in pavement structures interim report I - Analysis of mixes containing siliceous aggregates
(Jun-73)Sufficient heat can be transported from the surrounding ground to a bridge deck by heat pipes to both reduce the number of freeze-thaw cycles and to reduce the time during which the surface is below freezing. In a computer ... -
DEVELOPMENT OF GUIDELINES FOR SELECTION AND EVALUATION OF TACK COATS IN OKLAHOMA (FHWA-OK-18-02)
(Mar-18)Asphalt pavements are generally constructed by compacting asphalt mixes in multiple lifts to achieve the required density across thelayers. Also, depending on pavement preservation and maintenance plan, from time to time, ... -
Evaluation of bituminous mixes in pavement structures interim report III - A preliminary study of the use of the stiffness concept in minimizing
(Mar-76)Transverse cracking in flexible highway pavements is considered to be a serious and extensive problem by the asphalt paving technologist. There is a wide adreement that these cracks are caused primarily by the thermal ... -
