Product Manual of Asphalt Cold Mix Patching Material

1. Introduction

The asphalt cold mix patching material is a hi-tech road repair material, which can be used to repair various types of roads in all weathers and environments, such as asphalt concrete road, cement concrete road, parking lot, airport runway, bridge expansion joint, etc. In terms of cost, quality and use, it is better than common cold mix patching materials, traditional hot mix asphalt and . It has been extensively applied in the whole world owing to such features as simple application, long shelf life, excellent quality of repair, extensive application and being environment-friendly.

1.1 Product series of asphalt cold mix patching material

The products of asphalt cold mix patching material can be divided into three series: finished product of asphalt cold mix patching material, modified liquid asphalt and modified liquid asphalt additives (that we plan to purchase).

1.1.1 Finished product of asphalt cold mix patching material

Finished product of asphalt cold mix patching material is a mixture of modified liquid asphalt and aggregate mixed through certain mixing process. The recommended sizes are LB-13 and LB-10 and it can be adjusted to LB-5, LB-16, LB-19 and LB-24 to satisfy the special requirements of clients. The finished product is black granular solids, with slight petroleum odor, insoluble in water, with flashpoint of 177⁰C, insensitive to vehicle collision and static electricity and with stable characters.

1.1.2 Modified liquid asphalt

Modified liquid asphalt is the material for the production of asphalt cold mix patching material. It is the mixture of modified liquid asphalt additive, road asphalt and diesel oil by certain proportion. With the mixing equipment for traditional hot mix asphalt, in accordance with certain process, it can be mixed with aggregate to produce the asphalt cold mix patching material. There are two formulas to be used in winter and summer respectively. And special formula can be designed according to the requirements of clients to satisfy the application requirements under different weather conditions. It is in liquid state at normal temperature, with slight petroleum odor, insoluble in water, with flashpoint of 177⁰C and boiling point of 145⁰C~375⁰C, and with stable characters.

1.1.3 Modified liquid asphalt additives (that we plan to purchase)

Modified liquid asphalt additive (that we plan to purchase) is the main material for the production of asphalt cold mix patching material. It is a special chemical product, composed of various polymers. It modifies the characters of asphalt after being added into common road asphalt. It is oil liquid at normal temperature, with slight pungent odor, and with stable characters.

1.1.4 Size and package of the products of asphalt cold mix patching material

1.2 Key features of asphalt cold mix patching material

1.2.1 Applicable in all weathers and environment

The asphalt cold mix patching material can be used between -30⁰C~50⁰C; with excellent waterproof property, it can be applied in rain and snow and in pits and holes with accumulated water.

1.2.2 Simple application

When the asphalt cold mix patching material is adopted, it is unnecessary to use bonding oil and the prepared material can be fetched at any time when it is needed. It is unnecessary to use heavy construction machines and impact compaction, manual compaction or truck tire compaction can be adopted according to the road repair conditions.

1.2.3 Excellent quality of repair

The asphalt cold mix patching material has strong and bonding capacity. The unhealthy tendency of peeling off and map cracking will not easily appear on the pits and holes repaired. Repeated repair is not required. The life of repair is over 8 years.

The finished product of asphalt cold mix patching material can be stored in open air at normal temperature for 2 years. The storage time of bagged and sealed finished products is longer.

1.2.5 Simple production

The production process of asphalt cold mix patching material is simple and it can be produced locally with mixing equipment for traditional hot asphalt.

1.2.6 Open to traffic immediately

It is unnecessary to block up the area repaired with asphalt cold mix patching material and it can be open to traffic immediately, which greatly relieves the traffic pressure caused by road repair. 

1.2.7 Environment-friendly

No dust or black smoke is produced during the production and application of asphalt cold mix patching material and the finished product is insoluble in water, therefore it does not pollute the air and underground water and it is environment-friendly.

1.2.8 Extensive application

The asphalt cold mix patching material has good bonding capacity when used with asphalt concrete, cement concrete, metal surface and wooden surface and it can be used to repair and maintain various types of roads, such as express highway, highway, municipal highway and facility, airport, bridge expansion joint, etc.

1.2.9 Low cost of repair

The construction with asphalt cold mix patching material is not limited with weather condition and the size and quantity of pits and holes. The pits and holes can be repaired in time to avoid the expanding of them and save repair material. It is unnecessary to heat and mix during the repair. The material can be fetched according to actual amount required when it is needed and the rest material can be used for next repair and will not be wasted. It can be used 100%.

1.2.10 Remarkable social benefits

Road surfaces can be repaired with asphalt cold mix patching material in time to keep them new, ensure smooth traffic flow, enhance driving speed, decrease traffic accidents and repeated repairs of road surfaces and extend the life of roads.

2. Application and storage of asphalt cold mix patching material

2.1 Recommended repair depth of asphalt cold mix patching material

2.2 Recommended season and temperature for the application of asphalt cold mix patching material

2.3 Application method of asphalt cold mix patching material

2.3.1 Cleaning up the pits and holes

As to common repairs, remove stones and wastes in and around the pits and holes to be repaired. There shall not be any mud, ice or other things in the pits and holes. As to the repairs of express highway and municipal highway, the cutting edges of the holes and grooves to be repaired shall be neat. Remove all the wastes until the solid surface exposes.
