1- Asphalt. This may be the most common sealant used for gravel driveways, although technically the asphalt will actually bury the gravel, not seal it. Because gravel is a good base for asphalt, most of the work is already done. You will need to even out the gravel to remove any issues with the surface and then apply the asphalt on top.

E AC = asphalt concrete elastic modulus; E BS = base course resilient modulus; E SB = subbase course resilient modulus; M R (or E SG) = roadbed soil (subgrade) resilient modulus (used interchangeably) Stress Sensitivity of Moduli. Changes in stress can have a large impact on resilient modulus. "Typical" relationships are shown in Figures 3 ...

The content of crushed stone dust filler was replaced with a rate of 0%, 25%, 50%, 75%, and 100% to test Marshal stability to obtain the Optimum bitumen content and Optimum filler content.

In road structural layers, mixtures of crushed limestone with oil bitumen are used as a structural material (black crushed stone), or as a part of asphalt concrete organic-mineral mixtures.

Hot mix asphalt is known by many different names such as hot mix, asphalt concrete (AC or ACP), asphalt, blacktop or bitumen. For clarity, this Guide makes a conscious effort to consistently refer to this material as HMA.

Asphalt is a black, sticky substance that's derived from crude oil. It is used as a binder in road construction, binding the aggregate particles together to form a strong, cohesive material. On the other hand, macadam is a method of road construction where crushed stone layers are compacted and then bound together using tar or bitumen.
