瀝青和瀝青混凝土的主要區(qū)別在于它們的使用目的和材料組成：

　　The main difference between asphalt and asphalt concrete lies in their purpose of use and material composition:

　　使用目的：

　　Purpose of use:

　　瀝青是一種粘稠的物質(zhì)，用作道路鋪設(shè)時(shí)的結(jié)合劑，提高路面的穩(wěn)定性和耐久性。

　　Asphalt is a viscous substance used as a binder in road paving to improve the stability and durability of the road surface.

　　瀝青混凝土是將加熱的骨料、填充劑和瀝青按一定比例混合后，經(jīng)過(guò)壓實(shí)形成的材料，用于鋪設(shè)道路表面。

　　Asphalt concrete is a material formed by mixing heated aggregates, fillers, and asphalt in a certain proportion and compacting them, used for laying road surfaces.

　　材料組成：

　　Material composition:

　　瀝青是主要的結(jié)合材料，可以是石油瀝青、煤瀝青、天然瀝青或渣油等。

　　Asphalt is the main binding material, which can be petroleum asphalt, coal tar pitch, natural asphalt, or residual oil.

　　瀝青混凝土由粗集料（如碎石或軋碎礫石）、細(xì)集料（如石屑或砂）、礦粉和瀝青組成，有時(shí)還會(huì)加入聚合物和木纖維素等添加劑以改善性能。

　　Asphalt concrete is composed of coarse aggregates (such as crushed stone or crushed gravel), fine aggregates (such as stone chips or sand), mineral powder, and asphalt, and sometimes additives such as polymers and wood cellulose are added to improve performance.

　　性能特點(diǎn)：

　　Performance characteristics:

　　瀝青路面具有較好的柔韌性，能夠適應(yīng)路基、地基的不均勻沉降，并且修復(fù)速度快。

　　Asphalt pavement has good flexibility, can adapt to uneven settlement of roadbed and foundation, and has fast repair speed.

　　瀝青混凝土路面具有較小的空隙率，不透水，耐久性較好，但其造價(jià)和維護(hù)成本通常高于瀝青路面。

　　Asphalt concrete pavement has a small void ratio, is impermeable, and has good durability, but its cost and maintenance cost are usually higher than asphalt pavement.

　　使用壽命和維護(hù)：

　　Service life and maintenance:

　　瀝青路面的使用壽命相對(duì)較短，容易受到溫度變化的影響，冬季易脆裂，夏季易軟化，且耐老化性差。

　　Asphalt pavement has a relatively short service life and is easily affected by temperature changes. It is prone to cracking in winter and softening in summer, and has poor aging resistance.

　　瀝青混凝土路面的使用壽命較長(zhǎng)，強(qiáng)度高、穩(wěn)定性好，耐久性好，養(yǎng)護(hù)費(fèi)用低，適合承受重載交通。

　　Asphalt concrete pavement has a long service life, high strength, good stability, good durability, low maintenance costs, and is suitable for withstanding heavy traffic.

　　瀝青和瀝青混凝土都是道路建設(shè)中常用的材料，具體使用哪種材料取決于工程要求、預(yù)算和維護(hù)成本等因素

　　Asphalt and asphalt concrete are commonly used materials in road construction, and the specific material used depends on factors such as project requirements, budget, and maintenance costs
