Abrasion Testing

For a concrete pavement, the permeation specifications for the surface have a crucial influence on its durability. In this accelerated laboratory research, a surface treatment that combines lithium silicate chemistry with a reactive silicon catalyst was tested to typify the product longevity under traffic and against salt scaling. River gravel and limestone aggregates were used in two different mixture designs. Abrasion testing was conducted according to ASTM standards in which mass loss was recorded at different time intervals. A modification was employed using a diluted deicer simulated by 4 wt.% CaCl2 solution during 15 cycles of freeze/thaw testing. A model was proposed to relate the abrasion efficiency against load cycles of a treated surface to represent the longevity of a concrete pavement. Based on the abrasion coefficient and the texture wavelength of the pavement, it is shown that the life cycle under abrasion of a concrete pavement can be modeled. During the experimental procedures, the untreated concrete specimens were used as the control sample. Results from the abrasion and freeze/thaw testing of treated specimens indicated a lower level of cumulative loss damage, which confirms the benefits of using such products to extend the service life of a concrete pavement surface. The results of modeling indicated an increase of 14% of the ultimate load application to failure for the treated specimens, which indicates an increase in longevity of the pavement. Moreover, when exposed to freeze/thaw cycles, a limestone concrete showed less damage compared with the river gravel concrete mixture.

The cement concrete pavement surface are high, and its rigid structural integrity depends on the integrity of institutions and the plate itself, the overall rigidity of the lower body performance. However, the current board of cement concrete pavement breaking, cracking of roads has become an important common quality problems. For cement concrete road surface plate, the type of cracking, resulting in destruction of the reasons, etc., proposed prevention measures and precautions for disposal for the relevant officers.

EACCP is a new-type cement concrete pavement with better skid-resistance and less traffic noise. In this paper, skid-resistance and noise-reducing performance of EACCP are tested and analyzed by laboratory and outdoor tests. The results indicate that the relationship between BPN and EAD is followed the parabola variation laws. With the increase of EAD, TD decreases. And skid-resistance value exists the extremum. If BPN is targeted as skid-resistance optimization goal for pavement surface features, the optimized EAD is existed and approximately to 40~60. The relationship between BPN and TD is also followed the parabola variation laws which also suggests the existence of the optimized TD scope approximately to 0.8~1.0mm.The relationship between TD and EAD can be simulated by index variation laws. With the increase of EAD, TD decreases, which proves the evident noise-reducing performance of EACCP. And the reduction amplitude of noise increases with vehicular acceleration.

Surface macro-texture in rigid pavements plays an important role in providing safety (providing skid reswastant surfaces) for the traveling public. In general, macro-texture of cement concrete pavements had been measured through sand patch method in China. With the development of measurement technique, some quick methods were applied, such as laser cross-section instrument. But it was unsuitable for the grooving concrete pavement because of its restrictions on measurement principle. So measurement of concrete pavement surface macro-texture based on 3-D optical dense point clouds was introduced in this paper. First, 3-D coordinates of the pavement surface were obtained by the 3-D optical measurement system, then 3-D texture model would be rebuilt with self-programming softwwere, at last the Mean Texture Depth (MTD) of surface could be calculated and compwered with sand patch method. The article studies brooming, grooving and exposed-aggregate cement concrete pavements, and make a correlation analyswas between MTD values of these two methods. The results indicated that they had good correlation, and the measurement technique based on 3-D optical dense point clouds could be used to evaluate cement concrete pavement surface macro-texture quickly

Image Technique

In order to study the surface characteristics of exposed-aggregate cement concrete pavement, the measurement mechanism of surface texture depth was analyzed by using digital image technique. Based on the principle of least square and Table curve 3D software, two-dimensional digital image of road surface was reconstructed into three-dimensional space surface and a method of evaluating and measuring pavement surface texture depth was put forward. With this method， digital image samples were calculated and the results were compared with the results of conventional measurement method. The results indicate that exposed-aggregate cement concrete pavement has excellent road characteristics; there is a good correlation between the digital image technique and the traditional sand patch method and the relative error is less than 7 percent. Thus, the digital image technique is feasible in evaluating and measuring pavement surface texture depth.
