The conventional asphalt mixture was made using 10% mineral filler while for the lime-modified asphalt, the mineral filler was replaced with hydrated lime. The bitumen with penetration grade 60/70 was used and the content varied from 5.0 to 7.5%. Marshall stability and flow tests were carried out on …

Since lime is an effective asphalt modifier for improving the moisture resistance of asphalt pavements, is often used as mineral filler in asphalt concrete mixtures. Addition of lime can also improve pavement performance and durability. Hydrated lime added to asphalt can increase penetration and on …

For this purpose, two different asphalt binders, one aggregate type and two diverse filler types, hydrate lime and EAFSS were mixed together to prepare a set 12 asphalt mortars. Hydrated lime conventionally used as filler for asphalt mixture and EAFSS were combined with a conventional type of fine granite aggregate (<0.150 mm) at three ...

Hot-mix asphalt uses lime as an anti-stripping additive and as mineral filler. This adds years of life to highways, establishing a standard of safety and cost-effectiveness. Hydrated lime reduces stripping, rutting, cracking and aging. When hydrated lime is used alone, it substantially improves these properties, but it also works well in ...

High-viscosity modified asphalt (HVA) is widely used as the binder for permeable asphalt pavement, and hydrated lime (HL) attracts a strong technical interest as an effective moisture additive in asphalt for a long time. However, the application of HL in HVA has been rarely studied. The present study evaluates the influence of HL on the high-temperature rheological properties of HVA and ...

This research use of lime filler Sukaraja expected add durability layers of concrete pavement is asphalt damage caused by the weather and load traffic. This study attempts to know how much value characteristic Marshall on a mixture of concrete asphalt using lime filler. This research uses experimental methods that is with a pilot to get results, thus will look filler utilization lime on ...

Abstract. Read online. Mineral filler is one of important materials and affecting on properties and quality of asphalt mixtures .There are different types of mineral filler depended on cost and quality, the matter encourages us to achieve this study to evaluate hydrated lime filler effects on properties of asphalt mixes related with strength and durability.

Improve the asphalt cement-aggregate bond: Mineral filler crusher fines lime portland cement fly ash Carbon black: Extender: Substituted for a portion of asphalt cement (typically between 20 – 35 % by weight of total asphalt binder) to decrease the amount of asphalt cement required: Sulfur Lignin: Rubber: Increase HMA stiffness at high ...

Hydrated lime in hot mix asphalt (HMA) creates multiple benefi ts. Th e Benefi ts of HYDRATED LIME IN HOT MIX ASPHALT Written By: Dallas N. Little and Jon A. Epps 2001 ... Specifically, lime acts as an active filler, anti-oxidant, and as an additive that reacts with clay fines in HMA. These mechanisms create multiple benefits for pavements:

69 asphalt). Based on knowledge of how filler plays a role in the performance of HMA by providing 70 reinforcement of the mastic in HMA, this study concentrates on using lime kiln dust (LKD) as an 71 active filler, instead of hydrated lime (HL), a commonly used active filler for improving moisture 72 damage resistance of HMA.

The results show that the Marshall stability for the asphalt concrete with mineral filler ranges from 5.89 – 7.90 kN while that with hydrated lime ranges from 5.9 to 8.2 kN. The flow values for ...

To achieve this objective, the study is divided into four parts: (1) prequalification assessment of glass powder (GP), hydrated lime (HL), and stone dust (SD) fillers; (2) design of asphalt mixtures containing GP, GL, and SD fillers at different quantities (4, 5.5, 7, and 8.5% by weight of asphalt mix); (3) evaluation of mechanical and ...

Active functional groups mainly exist in heavy constituents and hydrated lime is active filler. Therefore, the strong combination between these materials strengthens interface bonding between fine particle filler and asphalt, consequently increasing the anti-fatigue performance of asphalt mortar (Smith and Hesp 2018).
