This book was released on 1995 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report (1) identified and characterized Virginia's nonpolishing aggregates in terms of their wet skid resistance, (2) compared the standard ASTM E 274-90 skid test to the British Accelerated Polishing Machine (BAPM) and British PendulumTester (BPT) system for pre-evaluating the skid resistance of nonpolishing aggregates, (3) compared the effect of different asphalt mixtures on pavement surface macrotexture using the ASTM E 965-87 sand patch method, and (4) briefly considered the effect of texturing on pavement surface friction. Recommendations for Virginia's Wet Accident Reduction Program (WARP) were drawn up from the results of these studies. Fifty-seven sources of nonpolishing aggregates, representing 18 lithologies, were studied. Skid testing of the 18 lithologies was carried out on 1,246 bituminous pavements, using the ASTM E 274-90 procedure. The aggregate groups showing the highest wet friction ranking were Valley Gravel, Fine Grained Granite, Lovingston Granite, Coastal Plain Gravel, and Diabase. Aggregates consistently exhibiting the lowest skid resistance were Aplite, Arch Marble, Slate, and Triassic Hornfels. The BAPM-BPT system showed little correlation with the skid test results. No significant differences were found between the overall skid numbers generated on 1-2 and S-5 asphalt mixes, but two trends were noted: 1) 1-2 pavements showed a faster decrease in skid resistance than S-5 pavements as accumulated traffic increased, and 2) where platy aggregates such as Slate and Arch Marble were used, S-5 pavements exhibited consistently higher long-term skid resistance than 1-2 pavements. One hundred and five sand patch tests were conducted to measure pavement surface macrotexture during the study. Macrotexture depth showed a higher correlation with skid numbers than any other factor investigated. Mixes exhibiting low skid resistance may do so because of rapid aggregate wear or the tendency of platy aggregate to orient horizontally, which both lower macrotexture depth. A brief survey of the effect of texturing suggests that Virginia's WARP should consider including pavement texturing as an alternative to repaving for wet accident hot spots.

Book Synopsis Water Sensitivity of Asphalt-aggregate Mixes by : Ronald L. Terrel
Download or read book Water Sensitivity of Asphalt-aggregate Mixes written by Ronald L. Terrel and published by National Research Council. This book was released on 1994 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research presented in this report was conducted to identify the important factors influencing the water sensitivity of asphalt paving mixtures, and to develop a test method to evaluate water sensitivity of asphalt concrete mixtures for mix design. The test method was to be performance related. A review of current procedures revealed that no single method was suitable for evaluation and related to field performance. Based on a hypothesis that air voids in the mixture may be the major source and cause of water damage, a test system was developed to evaluate the major factors that influence water sensitivity. The Environmental Conditioning System (ECS) was used to develop a test procedure that includes specimen preparation; measurement of permeability using air, water, or both; vacuum wetting; cycling at various temperatures; and continuous repeated loading while monitoring resilient modulus after each conditioning cycle.

Book Synopsis Development of a Prediction Model for Skid Resistance of Asphalt Pavements by : Arash Rezaei

Available in PDF, EPUB and Kindle. Book excerpt: The skid resistance of asphalt pavement is a major characteristic that determines the driving safety on a road, especially under wet surface conditions. Skid resistance is primarily a function of the microtexture and macrotexture of a pavement surface. Microtexture is influenced by aggregate surface characteristics and is required to disrupt the continuity of surface water film and attain frictional resistance between the tire and the pavement surface. Macrotexture is affected mostly by mixture design or aggregate gradation and contributes to skid resistance by providing drainage paths of water that can be otherwise trapped between a tire and a pavement surface. The increase in macrotexture contributes to preventing hydroplaning and improving wet frictional resistance, particularly at high speeds. While much research has been conducted in the past to identify material factors that affect skid resistance, there is still a need to develop a model for predicting asphalt pavement skid resistance as a function of mixture characteristics and traffic level. The purpose of this study was to develop such a model based on extensive laboratory experiments and field measurements involving different mixture types and aggregate sources. The model incorporates functions that describe the resistance of aggregates to polishing and aggregate size distribution. The aggregate resistance to polishing was quantified by measuring aggregate texture using the Aggregate Imaging System (AIMS) before and after polishing in the Micro-Deval device. The analysis in this dissertation demonstrates how this model can be used to design mixtures and classify aggregates that provide desirable skid resistance levels.
