Embodiment 1
[0035] In this embodiment, the geotechnical compaction instrument vibration molding method is adopted for the test piece, wherein the raw data of the cement-stabilized crushed stone road pavement mixture related constituent materials are measured. ， See Table 1 below.
[0036] Table 1. Statistical table of measured data of aggregate performance
[0037]
[0038] In the above table: the standard consistency of cement is 27.2%.
[0039] 1. After mixing according to the design ratio of the aggregate, the maximum relative theoretical density of the aggregate is calculated to be 2.706;
[0040] 2. Calculate the maximum relative theoretical density of the mixture when it contains cement:
[0041] 100÷(96÷2.706+4.0÷3.1)=2.719
[0042] In the formula: 96 is the proportion of aggregate in the mixture; 2.706 is the relative theoretical density of aggregate after mixing according to the design ratio of stone; 4.0 is the proportion of cement in the mixture; 3.1 is the relative densi...
Embodiment 2
[0072] In this embodiment, the same material as that in the first embodiment is used, and the moisture content of the mixture is designed by using the geotechnical heavy-duty compaction method.
[0073] In this design example, the measured value of the raw data of the relevant constituent materials of the cement-stabilized macadam road pavement mixture ， As in Table 1 above:
[0074] 1. After mixing according to the design ratio of the aggregate, the maximum relative theoretical density of the aggregate is calculated to be 2.706;
[0075] 2. Calculate the maximum relative theoretical density of the mixture when it contains cement:
[0076] 100÷(96÷2.706+4.0÷3.1)=2.719
[0077] In the formula: 96 is the proportion of aggregate in the mixture; 2.706 is the relative theoretical density of aggregate after mixing according to the design ratio of stone; 4.0 is the proportion of cement in the mixture; 3.1 is the relative density of cement .
[0078] 3. According to Table 1 above,...
