Book The Wearing Characteristics of Mineral Aggregates in Highway Pavements

Download or read book The Wearing Characteristics of Mineral Aggregates in Highway Pavements written by John W. Webb and published by . This book was released on 1970 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fifteen asphaltic concrete and seventeen portland cement concrete pavements located in Virginia were chosen for studies of aggregate wear and related wet pavement friction. Coarse aggregates from thirteen different geologic formations and quarry sources had been utilized in construction of the pavements. Field measurements of wet friction and pavement profiles and laboratory studies of aggregate petrography and surface microtexture were emphasized. The results of the research showed that aggregates can be classified into three categories based on their response to the wearing stresses of vehicle tires: (1) very homogeneous aggregates lacking significant zones and planes of weakness wear predominantly by abrasion; (2) aggregates marked by zones and planes of weakness wear predominantly by degradation or particle removal; and (3) aggregates of intermediate physical structure wear by a combination of abrasion and degradation. Polishing is most common with aggregates undergoing abrasion, the rate being dependent on the absolute hardness of the mineral constituents. Polishing removes micro-asperities and reduces the adhesion component of wet friction. The loss of macrotexture, or pavement relief, is common where degradation prevails. This loss, if excessive, retards water removal or drainage and adversely affects the hysteresis or tire deformation component of pavement friction. Optimum wet friction conditions are judged to prevail when a combination of abrasion and degradation creates an aggregate surface containing significant elements of both macro- and microtexture. It is concluded that careful petrographic study of aggregate mineralogy and texture will allow a high degree of prediction of the resulting surface configuration as aggregates wear under traffic.

Book A Review of Aggregate Selection Criteria for Improved Wear Resistance and Skid Resistance of Bituminous Surfaces

Download or read book A Review of Aggregate Selection Criteria for Improved Wear Resistance and Skid Resistance of Bituminous Surfaces written by SH. Dahir and published by . This book was released on 1979 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper includes a summary of an extensive literature review and the experience of the author in researching the properties of surface aggregates. It confirms that to resist wear, the aggregate must be hard and tough, and to resist polishing and surface slipperiness, the aggregate must wear slowly and irregularly. Particle shape, size, and gradation are important characteristics in providing optimum pavement surfaces, but ultimate aggregate performance depends largely on the aggregate mineralogy. A high proportion of hard minerals well cemented in a softer or a porous matrix will provide both high skid resistance and acceptable wear resistance. Within an aggregate particle, grain shape and size contribute to improved performance?medium to large and angular to subangular crystalline grains outperform minute and rounded non-crystalline grains. The performance history of an aggregate provides the best key to its expected future performance. In the absence of experience with an aggregate or when it is to meet new requirements, commonly used tests combined with petrographic analysis should provide sufficiently dependable initial information on the expected aggregate performance. A table that includes suggested target values for properties that enhance aggregate skid resistance and wear resistance is included in the paper.
