The study investigated the texture depth, skidding resistance and roughness index of various bituminous pavement surfaces in Johor, Malaysia. The texture depth is a measure of the macrotexture of the pavement surface, which is the coarse component of the surface aggregate and determine by sand patch test (SPT). While the microtexture, which is the measure of the aggregate interstices referred to as the resistance to polishing (PSV) of the aggregate, is determined by the British pendulum test (PTV). The surface roughness of the road surface is determined by using the Australian walking profilometer. The surface roughness of road constitutes the comfort and safety the pavement provides to the user.

Pavement skid resistance is one of the primary factors in highway safety. Pavements with adequate skid resistance reduce the number of crashes in wet conditions. The friction between pavement surface and vehicle tires is related to the macrotexture and microtexture of pavement surface. The macrotexture of asphalt pavement is dependent on aggregate gradation, while the microtexture is dependent on aggregate shape characteristics. Aggregates with angular shape and rough texture provide higher level of skid resistance compared to aggregates with smooth surface. In addition, pavement surfaces with high macrotexture provide higher skid resistance compared to those with low macrotexture. There were two main objectives of this study. The first object was to investigate and examine the surface and friction characteristics of various test sections of asphalt mixtures as well as seal coat surfaces. The test sections included different asphalt mixture types (e.g., dense graded, stone matrix asphalt, porous friction course), seal coat grades (Grade 1, Grade 2, and Grade 3), aggregate types (e.g., limestone, gravel, granite, sandstone), and the test sections were located in regions with different environmental conditions. The second objective was to develop a predictive model for skid resistance of seal coat surfaces and validate and revise an existing skid prediction model for asphalt pavements. Field testing primarily included measurements of coefficient of friction using a dynamic friction tester, pavement surface texture using a circular texture meter, and skid number using a skid trailer. The measurements were conducted on the outer lane where pavement surfaces experience significant polishing rates because most of the trucks use that lane. The resistance of aggregate to polishing and abrasion was studied using laboratory test methods. Several analytical models were developed to predict the friction and skid resistance of asphalt pavements and seal coat surfaces over their service life. These models incorporate parameters that describe aggregate resistance to abrasion and polishing, aggregate shape characteristics, aggregate gradation, and traffic level. These models were developed based on comprehensive field testing and aggregate laboratory characterization. Good correlations were found between the developed models and experimental data. The results demonstrated that aggregate and surface characteristics as well as traffic level have significant effect on skid resistance and rate of skid reduction. These models can be used during the mix design procedure to optimize the aggregate selection and aggregate gradation to produce mixtures with proper friction. In addition, these models can be incorporated in a Project Management System (PMS) at the network level to plan and program preventive maintenance activities to ensure that pavements have adequate skid resistance.

"This paper discusses the influence of roadway surface textures on the skid resistance, the speed-gradient, the wet-pavement accident rate, pavement wear, and the generation of tire-road interaction noise. The tendency of a vehicle to hydroplane is reduced by increasing the texture magnitude. Appropriate textures are developed by using open-graded asphalt friction surface courses and by grooving portland cement concrete with steel tines or a vibrating float while the concrete is plastic. Hardened pavements can be textured by grooving with a diamond saw or by resurfacing with an overlay. More development is needed in texture measurement techniques, especially in automating the stereo-photo interpretation method and the linear polarized laser technique"--Technical report documentation page

The report describes an evaluation and classification of pavement surfaces with respect to skid resistance. The study was conducted by means of a questionnaire survey of agencies within and adjacent to California, and by testing and examination of 45 existing pavement surfaces. The test program included standard skid tests at two speeds and additional tests with a smooth tire at one speed. Surface textures were measured by stereophotographs to obtain a "texture profile". The approximate cost of the surface, the amount of traffic exposure, and vehicle accident data were included in the evaluation. The pavement surfaces were ranked on the basis of skid number, speed gradient, and texture.
