The test instrument can record the peak value of splitting strength automatically. In the meantime, it also recorded the loading rate for verifying. All of the results were the last results after revising height, as shown in Table 5.18. Table 5.18. Test Results AK13AAK13BAC13AAC13B Voids (...
This could be the case in the roadways where the speed limit is low and at intersections where vehicles move very slowly. In these cases, the loading rate is low and the mode of failure due to both mechanical and moisture conditioning is primarily local premature surface failure. However, ...

The moisture damage is induced within a compacted sample by varying one or more of the following constraints such as pressure, temperature, cycle speed, liquid composition, and liquid level. FIG. 2 shows a preferred embodiment of the asphalt moisture damage tester (10). There are two test ...
1. Optimized design asphalt tank heating system, fast temperature rise speed, good heat preservation performance; 2. Folding spraying beam, asphalt spreading accuracy is high, can achieve three overlapping spreading, good uniformity, easy operatio...
17.2 hrs on record (11.4 hrs at review time) Posted: 8 October love the graphics and the music. not super expensive pass ass well. still playable free if you work really hard. 10/10. great cars, mechanics, and colors. Was this review helpful?
SBS modifier was added to virgin asphalt under the condition of 170℃, SBR modifier was added after high-speed stirring, and the compound-modified asphalt was formed after high-speed shear. SBS/SBR compound-modified asphalt is shown in Figure 1....
