Specifications for Road Tars: Indian Standards classify road tars for paving purposes into five grades — RT1, RT2, RT3, RT4, and RT5, meant for specific purposes. These are covered by "IS: 215-1995: Road tar: Specifications, Bureau of Indian Standards, New Delhi, 2000". The grades and specific uses are given below in Table 6.12:
Bamboo is a very fast-growing woody grass with a rapid maturation cycle (3–5 years) and is abundant across the tropics and subtropical regions (Hu et al. 2020)pared to trees bamboo is estimated to have a faster CO 2 absorption rate and higher oxygen production if managed correctly and can play a role in climate change mitigation and provide viable raw …
Waste materials can be added to asphalt concrete and bitumen in different forms depending on the type of waste and characteristics. Table 4 summarizes all reviewed materials in asphalt concrete and bitumen. The use of the correct form (e.g., as aggregates, fillers, or modifiers) of waste materials in asphalt concrete and bitumen is important to ...
Therefore, road base materials with lime-fly ash-PG binder had excellent performance. Gu et al. (2021) found that PG, slag, and cement with a weight ratio of 6:3:1 mixed with 5% micro silica fume (MSF) and 3‰ hydroxypropyl methylcellulose (HPMC) showed the best overall performance with a compressive strength of 28.8 MPa at 60 days and a ...
