Cold In-place Recycling (CIR) is a pavement rehabilitation treatment that involves cold milling the pavement surface and remixing emulsified asphalt, Portland cement or other modifiers to improve the properties. This treatment has been successfully used in Canada on roads that are highly deteriorated. Compared with CIR, Cold In-place Recycling with Expanded Asphalt Mixture (CIREAM) is very similar to CIR with the exception that it uses expanded (foamed) asphalt as the mixture instead of an emulsion. Both CIR and CIREAM meet the criteria for a sustainable pavement because of the safe, efficient, economic, and environmentally friendly characteristics.

冷式回收（CIR）是人行道康复治疗，涉及冷铣削路面表面并将乳化沥青，波特兰水泥或其他修饰剂混合以改善特性。这种治疗方法已在加拿大成功地用于高度恶化的道路。与CIR相比，与CIR的膨胀沥青混合物（CIREAM）与CIR非常相似，除非它使用膨胀（泡沫）沥青作为混合物而不是乳液，但与CIR非常相似。 CIR和CIREAM都符合安全，高效，经济和环保的特征，因此符合可持续人行道的标准。
