Slurry seal machines. Slurry seal is a cold-mix paving system that can remedy a broad range of problems on streets, airfields, parking lots, and driveways. The principal materials used to create slurry are aggregate, asphalt emulsion, and fillers which are mixed together according to a laboratory's mixed design formula. Heavy-duty pumps ...
The rutting test with the LPC rut tester (Figure 1) is a simulation test which consists in applying a 5 kN load with a wheel inflated to 0.6 MPa on the sample at 60˚C, for 30,000 cycles at a frequency of 1 Hz . Repeated wheel passage leads to the formation of a rut whose depth is the av-

The best method is described in the International Slurry Seal Association's TB - 109. It determines the maximum asphalt content of a slury mix. The loaded wheel test is intended to compact fine aggregate bituminous mixes such as slurry seal by means of a rubber tyred reciprocating wheel.
The wheel tracking test was conducted after curing with 154 lbs of vertical load on each wheel and at a frequency of 0.7 Hz (42 cycles per minute) for one hour at 25 °C. Wheel tracking tests are used to determine the dynamic stability value and rate of deformation of asphalt materials.

Common slurry seal is poor at preventing pumping distress when used as the under-seal coat in rigid pavement. In order to improve the water stability of common slurry seal and reduce the pumping distress in rigid pavement, this paper adopts the method of compositely modified slurry seal using waterborne epoxy resin (WER) and styrene-butadiene rubber (SBR) latex.
Asphalt seal-coat treatments are mainly a preventive maintenance procedure applied to the asphalt pavement surface to prevent or delay costly corrective measures (figure 2). Asphalt seal coats are surface treatments designed to seal and protect the asphalt pavement from harmful environmental conditions such as sunlight, rain, and snow.

A slurry seal is a mixture of dense graded aggregate, emulsified asphalt, fillers, addi-tives and water. The slurry seal is applied as a thin surfac e treatment using a specially designed slurry seal machine. Microsurfacing is much like slurry seal, but through the addition of polymers and the use of specialized design techniques, micro-surfacing
