The performance of porous asphalt is highly affected by environmental conditions, such as thermal and ultraviolet oxidation and/or freeze–thaw cycles, which lead to surface raveling, moisture damage and durability concerns of using porous asphalt in cold regions. ¹ Through proper strengthening of PA, it is possible to increase the useful lifespan of the pavement by more than 20 years.
· The CC pavement made of PQC are generally expected to sustain up to 45kg/cm2 of flexural stresses. In rigid pavements, the stresses are not transferred from grain to grain to the lower layers as in the case of flexible pavement layers. Slab action is capable of transmitting the wheel load cases through a much wide area below pavement slab.
Composite pavement. A composite pavement is a type of pavement that utilizes both asphalt and concrete. Typically, a concrete base layer provides structural capacity while an asphalt surface layer provides a wearing surface course. This pavement type can also be used in conjunction with roller-compacted concrete ( RCC) pavements, where the RCC ...

· CFRP composites, despite their light weight, have higher strength and greater hardness per unit weight of CFRP composite than glass fiber composites. This advantage is even more pronounced when compared to metallic materials. For example, experience tells us that CFRP materials weigh only 1/5 of steel under equal strength conditions compared to ...
· Asphalt Advantages. The use of asphalt pavement provides a fast, efficient, and economical construction process with unsurpassed versatility. Here we discuss the many advantages to using asphalt. Durability. Asphalt is a flexible pavement that can withstand occasional over-loads without serious damage.

Perpetual Pavement Concept •Asphalt pavements with high enough strength will not exhibit structural failures. •Distresses will initiate at the surface, typically in the form of rutting or cracking. •Surface distresses can be removed/ repaired relatively easily, •Before causing structural damage, •Leaving most of pavement in place,
The advantages of using composites include: 1. Resistance to a wide range of chemical agents including acid rain and salt spray, conditions under which metal parts would suffer. This results in much reduced maintenance and repair costs. 2. Resilience – the ability to deform and spring back to their original shape without major damage. Shape memory and impact tolerance are two of the biggest ...
