00:00My name is CSIR Structural Engineering Research Center
00:05Senior Principal Scientist
00:07Now we are developing a technology development
00:10What is the technology used to use?
00:13Bridges will be alternative to the expansion joint
00:15What is the expansion joint?
00:19If you look at flyover and flyover
00:23There are two metal strips
00:25What is the expansion?
00:27The bridges will be raised and expand
00:31The expansion of the bridge
00:33If you look at the stress of the bridge
00:36The expansion joint will be provided
00:39The expansion joint will be provided
00:41The maintenance of the joint
00:44There are problems
00:45The function of the additional stress
00:49The gap
00:51The members and columns
00:58The expansion of the joint
01:01will be changed
01:02The expansion joint is 25 years
01:03It will increase the life
01:03But, a bridge life is about 100 years
01:06When stick to the bridge
01:07In the journey of the bridge
01:08For makes it easy
01:09The expansion joint is usually
01:13It adds to the expansion joint
01:22Lifted the expansion jointUST
01:23I have a full technology development.
01:26The technology is doing the expansion joint and the expansion joint is doing the same thing.
01:31The path is physically the joint.
01:34The road continues.
01:36So, if you go to the next level, it will be a problem.
01:45It will create a problem with members.
01:46Overall, this is the life cycle cost.
01:50Conventional expansion joint compare.
01:52This is the life cycle cost.
01:55This is the technology we developed.
01:58This is related to our lab level testing.
02:03Temperature changes, fatigue cycle.
02:08This is the testing.
02:13Now the technology is almost ready.
02:17It is available for transfer also.
02:21It is available for the interested stakeholders.
02:24As I said, there is no gap.
02:28There is no gap.
02:29There is no gap.
02:30There is no gap.
02:31There is no problem.
02:33In fact, this is why the ride comfort increases.
02:37Also, fuel efficiency increases.
02:40This is an added advantage in the technology.
02:43Why is there a gap?
02:46Why is there a gap?
02:49Usually, if you look at each location,
02:53there is a temperature change.
02:56Every location, there is a temperature in summer time.
02:59There is a temperature in winter time.
03:00So, in the variation in temperature,
03:04the bridge will expand or shorten.
03:07So, the bridge will change the length of the bridge.
03:10There is no gap.
03:11It is no gap.
03:12There is no gap.
03:25So, the bridge will change the length of the bridge.
03:42Let's see.
03:44The bridge will develop the cadre of the bridge.
03:51It depends on the bridge.
03:51The bridge will change the length of the bridge.
04:00Cracks will be done by the same way.
04:08Slowly, the surface will be done by the surface, and the column will be created by the same problem.
04:14Once it is done by the same way, the overall life will be done by the same way.
04:19How do you think about the material?
04:24So, this material is a cement base material.
04:29So, it is concrete.
04:31It is similar material.
04:33It is core segregated.
04:37It is special type of fiber.
04:39So, the material is designed for this material.
04:44It is not a whole system.
04:48So, the whole system is reinforced.
04:54It is a disjoint.
04:58So, the whole system is developed.
05:01The material is one of the aspects.
05:04Is it your own bridge?
05:08So, we have to standardize it.
05:11We have to cut a 27m length.
05:13So, this is a bridge.
05:14We have to use a standard length.
05:19So, every length of the bridge.
05:21We have to standardize it.
05:24So, the length of the bridge is used.
05:26So, the length of the bridge is used.
05:29So, if this is day-to-day done,
05:29The next one looks good.
05:29There is what it is used to be used.
05:31Do it like this?
