(car engine rumbling)

3
00:00:13,050 --> 00:00:14,770
- [Narrator] The right
amount of pavement friction

4
00:00:14,770 --> 00:00:16,910
is critical for motor's safety,

5
00:00:16,910 --> 00:00:19,210
especially during wet weather.

6
00:00:19,210 --> 00:00:21,900
The Wet Surface Crash Reduction Program

7
00:00:21,900 --> 00:00:24,470
from TxDOT Traffic Safety Division,

8
00:00:24,470 --> 00:00:28,490
helps engineers identify
existing pavement friction,

9
00:00:28,490 --> 00:00:32,550
and the tools for specifying
new pavement surfaces

10
00:00:32,550 --> 00:00:34,850
that will meet friction demand.

11
00:00:34,850 --> 00:00:36,570
Even so in recent years,

12
00:00:36,570 --> 00:00:39,060
some flexible pavements have resulted in

13
00:00:39,060 --> 00:00:41,973
lower than expected skid value.

14
00:00:41,973 --> 00:00:43,150
To understand the problem,

15
00:00:43,150 --> 00:00:46,740
researchers with the Texas
A&M Transportation Institute

16
00:00:46,740 --> 00:00:49,600
are evaluating the criteria used

17
00:00:49,600 --> 00:00:52,933
to determine surface
aggregate classifications.

18
00:00:52,933 --> 00:00:55,450
- It's at TxDOT that we have a program,

19
00:00:55,450 --> 00:00:58,540
it's called the Wet Surface
Crash Reduction Program.

20
00:00:58,540 --> 00:01:00,150
This program provides the framework

21
00:01:00,150 --> 00:01:03,040
for identifying existing
pavement friction.

22
00:01:03,040 --> 00:01:05,580
Form 2088 is one of those
tools using the program

23
00:01:05,580 --> 00:01:08,460
to select those surfaces
that meet the demand.

24
00:01:08,460 --> 00:01:10,840
So really what this project
was trying to accomplish,

25
00:01:10,840 --> 00:01:13,100
was to evaluate that criteria

26
00:01:13,100 --> 00:01:15,270
and to make sure that the
form is really helping us

27
00:01:15,270 --> 00:01:17,920
make the best decisions for our pavements.

28
00:01:17,920 --> 00:01:20,810
- What we wanted to look at
was the criteria on the form,

29
00:01:20,810 --> 00:01:23,760
see if there is been research

30
00:01:23,760 --> 00:01:28,010
since the form was
created in the late '90s

31
00:01:28,010 --> 00:01:32,410
and update that criteria
based on the latest research.

32
00:01:32,410 --> 00:01:33,280
- [Robert] What the project did

33
00:01:33,280 --> 00:01:35,300
was found improvements in the program.

34
00:01:35,300 --> 00:01:37,160
So it triggered two research statements.

35
00:01:37,160 --> 00:01:41,040
So the first one was the
evaluation of surface types,

36
00:01:41,040 --> 00:01:43,970
pavement friction, and
wet weather accidents.

37
00:01:43,970 --> 00:01:47,950
The other project that is
needed as a result of this study

38
00:01:47,950 --> 00:01:51,210
is to incorporate some of the
findings in a different form.

39
00:01:51,210 --> 00:01:53,150
- We also recommended

40
00:01:53,150 --> 00:01:57,140
that they look at the Safety spreadsheet.

41
00:01:57,140 --> 00:02:00,080
This is another spreadsheet
that TTI developed

42
00:02:00,080 --> 00:02:01,140
through some research

43
00:02:01,140 --> 00:02:03,910
that the districts are starting to use.

44
00:02:03,910 --> 00:02:06,380
And a lot of the criteria
that's on the form,

45
00:02:06,380 --> 00:02:09,570
is also captured in
that Safety spreadsheet.

46
00:02:09,570 --> 00:02:12,210
So we think it's a good
efficient use of resources

47
00:02:12,210 --> 00:02:14,050
to just have one form.

48
00:02:14,050 --> 00:02:17,660
We found some information
about the aggregate

49
00:02:17,660 --> 00:02:19,250
that was not being captured,

50
00:02:19,250 --> 00:02:21,210
and so we made a recommendation

51
00:02:21,210 --> 00:02:25,560
to improve the surface
aggregate classification system

52
00:02:25,560 --> 00:02:28,590
to include some pavement
friction requirements

53
00:02:28,590 --> 00:02:29,640
into that system.

54
00:02:29,640 --> 00:02:32,390
- So safety is our priority here at Texas.

55
00:02:32,390 --> 00:02:35,430
Not only safety of our employees industry,

56
00:02:35,430 --> 00:02:37,820
but also it is critical to address safety

57
00:02:37,820 --> 00:02:39,679
of the traveling public.

58
00:02:39,679 --> 00:02:43,600
We think there's a critical
need that our criteria

59
00:02:43,600 --> 00:02:45,650
and our current form and
our current processes,

60
00:02:45,650 --> 00:02:48,470
need to make sure that the
right criteria is evaluated.

61
00:02:48,470 --> 00:02:50,580
We need to make sure that that aggregate

62
00:02:50,580 --> 00:02:54,110
and the selection form is
accurately tying friction

63
00:02:54,110 --> 00:02:56,350
and reducing those accidents.

64
00:02:56,350 --> 00:02:59,300
We wanna make sure that the
traveling public is safe.
