Literature Review
Cavey et al. 1995 conducted a combined field and laboratory
study to examine the suitability of low-cost materials from recycled
concrete aggregate stabilized with portland cement. Split
tensile, flexural strength, and toughness tests were conducted.
Significant enhancements in properties were observed due to stabilization.
Another study by NCHRP 1992 highlighted the importance
of flexural strength in designing a pavement structure
with stabilized aggregate base. Flexural strength, tensile strength,
and compressive strength of stabilized aggregate bases were
examined.
According to Ioannides and Peng 2004, many state DOTs
and other transportation agencies are actively pursuing
mechanistic-based techniques that are expected to improve the
design of pavements. Three issues are considered important in
this respect: 1 failure models; 2 material characterization procedure;
and 3 new techniques to account for the stochastic nature
of pavement problems. Ioannides and Peng 2004 addressed
some of these issues in their work, where a fracture mechanicsbased
approach was used to predict the structural behavior of
pavements. In their study, the Hillerborg’s fictitious crack model
was used to simulate the crack growth in concrete slabs. A general
purpose finite element software ABAQUS was utilized to examine
the fracture behavior of these slabs.

Cavey等人,在1995年开始了一项多领域实验的研究,研究能否从可回收的硅酸盐水泥从找到合适的低成本材料,测试项目包括拉伸强度,弯曲强度和硬度,在实验中明显的可以看到稳定性的增强是物质的性能明显提高。另一项由NCHRP主导的研究表明延展性的在路面基础的稳定性有很重要的作用。弯曲强度,拉伸强度和地面地基的压缩强度也都被做了相关的测试。

根据Ioannides and Peng在2004年的研究,很多国家和机构都在积极做机械基础技术的研究以提高道路的设计,其中有三点是比较重要的,第一故障模型,第二是材料表征过程,第三是新技术对路面随机影响的问题。Ioannides and Peng在2004年的研究报告中提到了这几点,其中他们利用断层机械基础在预测道路的结构行为。在他们的研究中,the Hillerborg使了虚拟裂缝模型来模仿混泥土路面裂缝的增长,一般是使用软件ABAQUS来研究这些砖断裂行为。
