The increase of crude oil prices in recent years resulted in an increase in bitumen prices as crude oil is origin for bitumen, asphalt and in other hand the fly ash from the power generating plants causes severe disposal problems. The main purpose of this project is to study the possibility of using fly ash as mineral filler in Bituminous paving mixes. Fly ash, a coal combustion product once treated as waste and disposed in landfills, is used today in substructure and road works. The research of fly ash properties may solve the problems of treatment and intelligent use of this residual material. This Marshall stability test is employed to determine the properties like stability, flow value, air voids, voids in mineral aggregate VMA , voids filled with bitumen VFB for a Dense Bituminous Macadam DBM mix. The experimental work is carried out by using specifications from MORTH Ministry of road transports and highways, specifications for road and bridge works,5th revision .By replacing the stone dust with fly ash at the levels 4 , 6 and 18 the results are compared. The variation of properties, optimum bitumen and fly ash contents are evaluated. It is observed that the mixes with fly ash as filler not differ much in properties when compared with control mix and satisfy desired criteria specified by a much higher margin. Hence, it has been recommended to utilize fly ash wherever available, not only reducing the cost of execution, but also partly solve the fly ash utilization and disposal problems.

Asphalt Paving is fully equipped and experienced in Hot Asphalt Paving as per MoRTH Specifications. Most common applications include – Semi Dense Bituminous Carpet, Dense Bituminous Carpet, Bituminous Macadam Course and Bituminous Course laid in thickness of 40 – 50 mm. Our teams have the expertise to execute Hot Asphalt works with 60/70 grade Bitumen as well as Polymer Modified Bitumen (PMB) , Crumb Rubber Modified Bitumen (CRMB) and also emerging world class technologies like Stone Matrix Asphalt (SMA) courses. Asphalt paving is known for its durability and resilience. It is this strength which makes asphalt pavement the best and most popular choice for applications such as driveways, parking lots, roadways and airstrips. While asphalt requires annual maintenance to maximize its lifespan, the investment is far less expensive than other pavement types #maintenance #like #parking #investment #rootbuildconprivatelimited #highwayconstruction

Tarmacadam

Tarmacadam is the cheapest and quickest method of surfacing. The official term for it is bituminous macadam or ‘Bitmac’ for short. Tarmacadam has become a popular, although technically incorrect term for both bitumen and asphalt which is used to surface pavements, highways and even internal floors.

Tarmacadam takes place by mixing together smaller aggregates and was first done by Jon MacAdam in the 19th century. After this creation of the now commonly used material it became used throughout different countries as the road resurfacing product of choice. In present times we have moved on from using natural tar and now use bitumen from the oil industry.

Hot Rolled Asphalt (HRA)

Hot rolled asphalt is often abbreviated as HRA is a dense mixture of mineral aggregate, sand, filler and bitumen that complies with EN 13108 and the NRA Specification for Road Works.

This is commonly used on public highways as it is an incredibly hard wearing and durable material. Roads are dangerous and this is why HRA is a popular choice when it comes to safety as it is skid resistant and stays in tack for a long time.  On top of this, there is a high ratio of sand in the mix which creates a low percentage of air voids when it is compacted.  When used to resurface roads in Sussex the high PSV chippings are applied to the hot-laid material and rolled in to form a skid resistant surface.
