Influence of cement on low-temperature property of granite asphalt mixtures
Combined with the application of granite asphalt mixtures in the pavement project along the Ma-Wu Expressway. In this paper, the amount of 20%, 40%, 60%, 80% cement was in equivalent replacement of common filler. The effects of cement on low-temperature property of granite asphalt mixtures were investigated by indirect tensile strength and three-point bend test, obtained the variation of cement with different admixture amounts influence on granite asphalt mixtures, than the optimum mix amount has been found. Experimental results showed that the cement additive improved the low-temperature property and the optimum mix amount of cement was 40%∼60%, which possesses guiding significance for ensuring bituminous pavement project quality.
Th e Benefi ts of HYDRATED LIME IN HOT MIX ASPHALT
This report discusses the benefits of using hydrated lime in hot mix asphalt paving mixtures. Some of these benefits include: control of water sensitivity, use as an antistrip agent to inhibit water damage, stiffens asphalt binders when used as a mineral filler, improves resistance to crack propagation, decreases damage from oxidation, improves moisture durability and stability by changing the properties of clay fines.
The correspondence principle of linear viscoelasticity for problems that involve time-dependent regions
Abstract A version of the correspondence principle of linear viscoelasticity theory that is based on an alternative form of the Laplace transform inversion theorem and is valid for bodies that occupy time-dependent ablating regions of space is presented and used to derive solutions to certain thermoviscoelastic boundary value problems for hollow ablating right circular cylinders. The application of this version of the correspondence principle to bodies occupying fixed regions of space but for which the boundary regions, over which different types of boundary conditions are specified, vary with time is investigated and exploited to study the thermoviscoelastic problem of an infinite body containing an extending penny shaped crack on whose surface various thermal conditions may prevail.
