Dr.Fixit PidiJoint 6297 is a high modulus asphaltic plug joint formulated for roads with heavy traffic. It is designed for joints 500 mm width and minimum of 100 depth to accommodate low to medium three dimensional movement range.
Dr.Fixit PidiJoint 6297 is a proprietary blend of thermoplastic compounds. Key ingredients are bitumen, polymers, fillers, and additives. It is formulated to combine easy flow at application temperatures with flexibility and slump control during service life. It is used with aggregate to ensure high load bearing capacity and resistance to wheel tracking. The combination of highly flexible joint sealant and single sized interlocking aggregate allows the system to provide excellent anti rutting quality.quality.
Features and Benefits
Easy to melt, applied hot and in a fluid condition, with temperatures up to 180°C.
Resist overheat during melting process.
Excellent elasticity accommodating expansion and contraction of bridge joint.
Will not peel/crack even under long flooding immersion.
Excellent joint adhesion & highly durable
Area of Application
Expansion joints on high traffic bridges on roads and highways.
Method of Application
1. The eurfacing is cut to the specified width in the carriageway using a floor saw and a trench is excavated. 2. This cut-cut together with the previously formed recess in the verge / central reserve is cleaned and dried with hot compressed air. 3. The expansion gap is then caulked and the deck sealed with hot binder. If specified, in joint hydraulic relief are installed, Metal bridging plates inserted over the gap and the entire trench tanked with binder. 4. Melt approiate amount of Dr.Fixit PidiJoint 6297 in hot joint applicator. And pour Dr.Fixit PidiJoint 6297 into prepare joint as a primer. 5.The aggregate is heated and pre-coated with the binder subsequent layers are placed.
For 1 coat heat 3/4 inch aggregete size at 180 °C to remove water vepor prior to adding melted Dr.Fixit PidiJoint 6297 onto heated aggregate. Wait for aggregate is fully coated with Dr.Fixit PidiJoint 6297 pour into prepare joint.
For 2 coat heat 3/16 inch aggregate size at 180 °C prior to adding melted Dr.Fixit PidiJoint 6297 onto heated aggregate. Wait for aggregate is full coated with Dr.Fixit PidiJoint 6297 pour into prepare joint an compact the surface level.
Finally the joint is flooded with binder to the finished profilr and allowed to cool before the final layer is applied-this is stone rich, brought marginally above the road suface and then compacted to the level of the adjacent carriageway. Normally the joint can be trafficked in 3-4 hours, but this will depend on the ambient temperature, depth of joint and the general weather conditions. 7. A final application of binder may be necessary to blend in any small interstices which may appear on the surface of the joint whilst cooling. Anti-skid dressing is applied to the joint. 8. Clean surface, tape around joint surface edge, and pour melted Dr.Fixit PidiJoint 6297 to level and seal fo joint within tape area, wait for 1 to 2 hour prior to opening for traffic.
Cleaning
Tools and equipment should be cleaned immediatey with kerosene or mineral turpentine.

Safety & Heath precautions
In case of fire use dry chemical or carbon dioxide or sand. Do not use water.
If molterial comes onto contact with skin, immerse the injured part unde running cold water, and obtain medical advice immediately.
Do not allow water to come into comtact with molten material. This mav cause it to boil over.
